Product details
Overview
MSP430F4152IRGZR from Texas Instruments is an ultralow-power 16-bit RISC mixed-signal microcontroller with 16 KB Flash, 512 B RAM, integrated 10-bit 200-ksps ADC, dual USCI interfaces (UART/IrDA/SPI + I²C/SPI), and LCD driver supporting up to 144 segments - deployed in battery-powered sensor nodes and portable meters.
For engineers reviewing the MSP430F4152IRGZR datasheet, MSP430F4152IRGZR pinout, MSP430F4152IRGZR application, or MSP430F4152IRGZR equivalent, key selection criteria include active-mode current (220 µA @ 1 MHz, 2.2 V), wake-up time (<6 µs from LPM3), LCD segment drive capability, and QFN-48 package compatibility with embedded space constraints.
Technical Context
The MSP430F4152IRGZR implements a 16-bit CPU with constant generator and seven addressing modes, executing register-to-register instructions in one CPU cycle. Its FLL+ clock system stabilizes the DCO to multiples of ACLK (e.g., 32.768 kHz crystal) and delivers MCLK, SMCLK, and ACLK with programmable dividers.
It integrates two independent 16-bit timers: Timer_A3 (3 capture/compare registers) for PWM and interval timing, and Timer_A5 (5 capture/compare registers) for advanced input capture and waveform generation - both support interrupt-driven operation and DMA-triggered data transfer via DTC.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with 125-ns instruction cycle; register-based execution enables high code efficiency in memory-constrained applications. |
| Flash / RAM | 16 KB + 256 B Flash program memory and 512 B RAM - sufficient for firmware with real-time sensor processing and LCD UI logic. |
| ADC Performance | 10-bit, 200-ksps SAR ADC with internal reference, sample-and-hold, autoscan, and DTC - supports concurrent sampling across 8 channels without CPU intervention. |
| Power Modes | Five low-power modes including LPM4 (0.1 µA RAM retention); wake-up from LPM3 in <6 µs enables rapid response to external events. |
| LCD Driver | Integrated LCD_A module driving up to 144 segments in static/2-/3-/4-MUX configurations with software-controlled contrast via regulated charge pump. |
| Communication | USCI_A0 (UART/IrDA/SPI) and USCI_B0 (I²C/SPI); note: USCI_B0 is disabled in 48-pin RGZ package per SLAS648E p.5. |
| Supply Range | 1.8 V to 3.6 V operation - compatible with single-cell Li-ion, LiFePO₄, or dual-AA battery systems without external regulation. |
Pinout & Package
Package: 48-pin QFN (RGZ), 7 × 7 mm body, 0.5 mm pitch, thermal pad (DVSS-connected). Pinout validated per SLAS648E Rev. March 2011, pages 4 and 6–9.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RST/NMI/SBWTDIO | Reset / NMI input / Spy-Bi-Wire I/O | Active-low reset initiation; dual-function JTAG/Spy-Bi-Wire debug interface using single-wire protocol for programming and emulation. |
| P1.0/TA0.0/S31 | GPIO / Timer0_A3 CCI0A / LCD segment | Primary UART TX pin when BSL active; supports timer capture, compare output, and direct LCD segment drive. |
| P1.1/TA0.0/MCLK/S30 | GPIO / Timer0_A3 CCI0B / MCLK output | Primary UART RX pin during BSL; also outputs system clock for external synchronization or test measurement. |
| P6.0/TA1.2/A2/CA4 | GPIO / Timer1_A5 Out2 / ADC10 A2 / Comparator A4 | Shared analog input for ADC and comparator; enables simultaneous threshold detection and digitization on same signal path. |
| P7.4/TA1.4/A0/CA2 | GPIO / Timer1_A5 CCI4B / ADC10 A0 / Comparator A2 | Analog input channel A0 with dedicated timer capture capability - supports time-stamped edge detection on analog events. |
| AVCC / AVSS | Analog supply terminals | Separate analog power domain (pins 48 and 46) isolates noise-sensitive ADC and comparator circuitry from digital switching. |
| DVCC / DVSS | Digital supply terminals | Digital power rails (pins 3 and 6) feed CPU, timers, and USCI modules; thermal pad must connect to DVSS for thermal management. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F4132IRGZR | 8 KB Flash, identical RAM (512 B), same peripherals and pinout - reduced code capacity only. | Suitable for simpler firmware with smaller footprint; no change to PCB or peripheral drivers required. | Select when application code fits within 8 KB and cost sensitivity outweighs future firmware headroom. |
| MSP430F2617TPM | 116 KB Flash, 8 KB RAM, enhanced USCI (two UART/I²C/SPI), but 64-pin QFP only and no integrated LCD driver. | Requires external LCD bias IC and larger board area; targets complex applications needing more memory and communication flexibility. | Choose only if LCD functionality is unnecessary and higher processing headroom justifies added cost and layout complexity. |
Compared with MSP430F4132IRGZR, the MSP430F4152IRGZR provides 100% pin-compatible upgrade path with double Flash for feature-rich firmware; versus MSP430F2617TPM, it trades memory scalability for integrated LCD support and smaller QFN footprint - critical for space-constrained portable designs.

FAQ
What is the maximum operating frequency of the MSP430F4152IRGZR?
The MSP430F4152IRGZR operates at up to 8 MHz via its digitally controlled oscillator (DCO), stabilized by the FLL+ module using an external 32.768 kHz crystal. Its 125-ns instruction cycle time corresponds to 8 MHz CPU clock, confirmed in SLAS648E Section 1. The device achieves this speed across the full 1.8–3.6 V supply range without external clock source.
Does the MSP430F4152IRGZR support hardware I²C communication?
Yes, the MSP430F4152IRGZR supports hardware I²C through USCI_B0, but only in the 64-pin QFP (PM) package. In the 48-pin QFN (RGZ) package - including the MSP430F4152IRGZR - USCI_B0 is not available per SLAS648E page 5. Designers must use USCI_A0 in SPI mode or implement bit-banged I²C on GPIO for RGZ variants.
How many LCD segments can the MSP430F4152IRGZR drive, and what mux configurations are supported?
The MSP430F4152IRGZR drives up to 144 LCD segments using its integrated LCD_A module, supporting static, 2-MUX, 3-MUX, and 4-MUX configurations. This capability is enabled by dedicated segment and common I/O pins (P5.0–P5.7, P6.0–P6.7, P7.4–P7.6, etc.) and software-controllable charge pump voltage - all documented in SLAS648E Sections 1 and 17.
What debug interface does the MSP430F4152IRGZR use, and is JTAG supported?
The MSP430F4152IRGZR uses the Spy-Bi-Wire (SBW) interface via RST/NMI/SBWTDIO and TEST/SBWTCLK pins for programming and debugging - a 2-pin subset of JTAG. Full 4-wire JTAG is not supported on this device; SBW provides equivalent functionality with reduced pin count, validated in TI's MSP430x4xx Family User's Guide (SLAU056) and SLAS648E Section 16.
Is the MSP430F4152IRGZR RoHS compliant and qualified for industrial temperature range?
Yes, the MSP430F4152IRGZR is RoHS compliant and rated for operation from –40°C to +85°C, as specified in the "AVAILABLE OPTIONS" table on SLAS648E page 2. The "I" in the part number denotes industrial temperature grade, and TI's official packaging documentation confirms lead-free (Pb-free) construction and JEDEC-standard moisture sensitivity level (MSL) 3 for the RGZ package.
